While the Ruger 10/22 is a favorite rimfire rifle for speed shooting competitions and recreational shooting, it's not uncommon for the factory bolt to need a complete re-work for the gun to function at its best. Fix common 10/22 bolt issues- without the need for a gunsmith- with the new "KrossFire" CNC-Machined Bolt from RimEdge. CNC-Machined from hardened tool steel, the "KrossFire" Bolt features a pinned firing pin to restrict the vertical movement and strike the cartridges in a consistent manner, reducing misfires. The CNC-machining process allows for precise headspace measurement, ensuring the bolt face sits flat against the barrel and Mfg: Tandemkross
